Virtual gateway: A Direct Connect virtual gateway is attached to the enterprise router. VPN gateway: A VPN gateway is attached to the enterprise router. Peering connection: The enterprise router connects to another enterprise router in a different region.
Global DC Gateway: In this example, virtual interface VIF-A is associated with global DC gateway DGW-A, and VIF-B associated with DGW-B.
VPN gateway Peering connection Global DC gateway In the Route Policy drop-down list, select a route policy.
Propagations manually created in the custom route table of the enterprise router for attachments, such as global DC gateway 1, VPC 1, VPN gateway 2, and global DC gateway 2 attachments.

Traffic from the virtual interface is forwarded to the virtual gateway through the local gateway of the virtual interface. Traffic is forwarded from the virtual gateway attachment to the enterprise router.
A route policy can be applied to the following types of attachments: Virtual gateway attachments Peering connection attachments VPN gateway attachments Global DC gateway attachments An enterprise router can use a route policy to: Advertise only the routes that match the conditions
Flow logs can capture traffic of the following types of attachments: VPC Virtual gateway VPN gateway Peering connection Global DC gateway Creation Process Before creating a flow log for an enterprise router, you need to create a log group and a log stream on the LTS console.
VPN gateway Global DC gateway: Direct Connect global DC gateway VPC Resource Mandatory In the resource list, select the resource whose traffic information is to be collected. vpc-ab Log Group Mandatory Select a log group.
Step 4: Create a Virtual Gateway Attachment to the Enterprise Router Create a Direct Connect connection to connect the on-premises data center to the cloud over a line you lease from a carrier. Create a virtual gateway and attach it to the enterprise router.
The request is not completed because the server receives an invalid response from the upstream server. 503 Service Unavailable The request is not completed because the system is temporarily abnormal. 504 Gateway Timeout The gateway timed out.
After the global DC gateway is attached to the enterprise router, Enterprise Router will automatically: Associate the global DC gateway attachment with the default route table of the enterprise router.
You can also attach a Direct Connect virtual gateway or global DC gateway or a VPN gateway to allow an on-premises data center to communicate with VPCs through Enterprise Router and Direct Connect. Use Cloud Firewall (CFW) to protect traffic between VPCs.
The default PrefVal values of routes for different types of enterprise router attachments are as follows: Virtual gateway attachments: 100 Peering connection attachments: 60 VPN gateway attachments: 80 Global DC gateway attachments: 100 NOTICE: Changing the PrefVal value of a route

Enterprise routers use the Border Gateway Protocol (BGP) to learn, dynamically select, or switch between routes, thereby ensuring the service continuity and significantly improving network scalability and O&M efficiency.
